Problem

Consider the problem of applying EM to parameter estimation for a variable X whose local probabilistic model is a noisy-or. Assume that X has parents Y₁, . . . , Y_k, so that our task for X is to estimate the noise parameters λ₀, . . . , λ_k. Explain how we can use the EM algorithm to accomplish this task. Utilize the structural decomposition of the noisy-or node.
